Tiffany & Co.’s new HardWear collection is only just being released in stores and online today, but fashionable celebrities have already been spotted wearing the chic designs.

Kate Mara wore her 18 karat yellow gold wrap necklace ($11,500) for a daytime stroll in a casual sundress, while Karolina Kurkova accessorized an all-white ensemble with the ball hook earring in 18 karat yellow gold ($1,250). Scarlett Johansson attended an event where her cropped hair showed off the chain link earrings ($5,000).

For Tiffany & Co.‘s Los Angeles event celebrating Tiffany HardWear, co-hosts Zoë Kravitz and Riley Keough both of course wore pieces from the collection, as did Vampire Diaries actress Kat Graham.

The collection of 18k gold and sterling silver pieces is a far cry from the classic engagement rings and fine jewelry styles often associated with the brand; instead, these items lean more towards the modern design side of Tiffany & Co.

Interestingly enough, the collection, comprised of earrings, bracelets, rings and necklaces, is inspired by a unisex bracelet from the 1971 Tiffany Archives. It “embodies the strength and spirit of the modern woman, imbued with the soul of New York,” per a statement from the brand, so it’s fitting that Lady Gaga is starring in the Legendary Style campaign for the HardWear collection—the ad debuted during Super Bowl LI.

The collection ranges from pieces like a dangling ring ($1,175) to wrap bracelets ($6,500) and triple drop earrings ($2,500).

Now that the HardWear collection is available online and in Tiffany stores worldwide, you’re sure to see even more stars wearing the jewelry. Scroll through the slideshow above to see all the chic ways celebs have styled the HardWear collection.
